Fossil fuels, such as coal, oil, and natural gas, are formed from the remains of ancient plants and animals and take millions of years to replenish, making them non-renewable.

Agriculture, particularly the expansion of cattle ranching and soybean farming, is the leading cause of deforestation in the Amazon rainforest.

Nitrogen is not a greenhouse gas, as it does not trap heat in the atmosphere like carbon dioxide, methane, and water vapor do.

Recycling involves collecting and processing waste materials to create new products, reducing the amount of waste sent to landfills and conserving natural resources.

Nuclear energy is not considered a renewable energy source as it relies on uranium, a finite resource, to generate electricity.

Climate change, particularly rising ocean temperatures, is the primary cause of coral bleaching in the Great Barrier Reef.

Light pollution refers to excessive or misdirected artificial light, which can have negative impacts on human health, wildlife, and the night sky.

Reducing involves minimizing the amount of waste generated at the source, such as by using reusable products, buying less, and avoiding single-use items.

Biodiversity does not directly reduce the risk of natural disasters, although it can contribute to ecosystem resilience and the ability of ecosystems to recover from disturbances.

Composting involves breaking down organic materials, such as food scraps and yard waste, into a nutrient-rich soil amendment that can improve soil health and fertility.

Monoculture, the practice of growing a single crop on a large area of land, is not considered sustainable as it can lead to soil depletion, increased pest problems, and reduced biodiversity.

Conservation involves managing and protecting natural resources, such as forests, water, and wildlife, to ensure their long-term availability and sustainability.

Geothermal energy, while sustainable, is not considered a renewable energy source as it relies on the heat from the Earth's interior, which is a finite resource.

Restoration involves repairing and restoring damaged ecosystems, such as forests, wetlands, and coral reefs, to their natural state.

Thermal pollution refers to the release of excess heat into the environment, typically from industrial processes or power plants, which can have negative impacts on aquatic ecosystems.
